PROBLEM TO BE SOLVED: To provide a screw conveyer device for conveying kneaded sand capable of easily removing adhered sand to a trough or a screw, or for realizing a screw structure for preventing the kneaded sand from being adhered and smooth flow of the kneaded sand by loosing and conveying the kneaded sand in a simple structure. SOLUTION: In this screw conveyer device for conveying kneaded sand, a rotating shaft rotated by a motor is disposed in the trough having an input port in its upper part and a discharge port in its lower part, and a scraper is spirally mounted to the rotating shaft. Many blow nozzles for injecting compressed air are arranged in the trough at an interval, the motor is connected to an ammeter and communicated to a solenoid opening/closing valve for switching between supply and block of the compressed air to many blow nozzles, and the ammeter and the solenoid opening/closing valve are electrically interconnected via a controller.
